α-lithio α-trimethylsilyl cyclopropanes have been prepared by two different routes. They have been tested as precursors of alkylidene cyclopropanes, cyclopropylidienes and α-silyl α-vinyl cyclopropanes.
Polyenes bearing an alkylidenecyclopropane moiety are oxidized selectively at the alkylidene moiety or at the other C,C double bond(s) depending upon the nature and the relative number of substituents present at each unsaturation.
